Today I went to sign onto my friends and my custom modpack server that we created and I used Teamviewer to get into the server PC, and everytime I go to restart it I seem to get the same crash report every time. I have narrowed it down to be the itemducts from Thermal Expansion, but that is about it, could anyone else help me with it or give any advice? The top bit of the crash-report is in the spoiler below, any help would be appreaciated.
